Overview

Fucus vesiculosus is a type of brown seaweed that grows in the Baltic Sea, Atlantic Ocean, and North Pacific Ocean. The whole plant is used as medicine.

Fucus vesiculosus contains varying amounts of iodine. Iodine might help prevent or treat some thyroid disorders. Fucus vesiculosus also might have antidiabetic effects and affect hormone levels.

People use Fucus vesiculosus for thyroid disorders, obesity, aging skin, constipation, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse Fucus vesiculosus with algin, bladderwort, blue-green algae, ecklonia cava, or laminaria. These are not the same.
